This. Someone close to me worked there for 7 years. The level of secrecy is crazy. Like, dysfunctional-hard-to-do-your-work and stay-up-all-night-working-before-a-launch-because-you-are-only-finding-out-about-it-then crazy. Talking in public about your job would not end well.
Therefore I'm surprised about the OP. Sure they have a specific employment contract in place with a batallion of lawyers drooling on their preys, so what does the OP risk?
